I currently have a legacy Omeka 1.4 site for my research on one webhost & domain (rwany.gobiwebdesigns.com), but I am not the web admin and do not have the control panel access. So, I decided to migrate to a new webhost & domain (rwanysibaja.com) where I have acces to the cpanel. I have also created a subdomain - animales.rwanysibaja.com - where I have just installed Omeka 2.5.
Question: without updating the old Omeka 1.4 to 2.1, in order to use the Api Import plugin, what is the best way to migrate content (items, collections, exhibits, etc) to the new 2.5 site? If I follow the 6 steps at https://omeka.org/codex/Moving_to_Another_Server, will I run into any conflicts when replacing certain files? And are there any plugins I should go ahead and install before migrating my content? (NOTE: I do have access to the files on the old Omeka site thru Filezilla, and created a backup of the entire 1.4 site on my hardrive)
